To all wit/)nt t 'nw/y concern.'

Be it known that l, Gnonon W. @envien a citizen of the United States, residing et No. 17 Murray street, N ew York city, N ew York, have invented certain new und useful im provenients in liubricetors, oi which the following is a specification.

My invention is an automatic force-'feed lubricator, and while designed particularly for use in connection with automobiles for lubricating the dillcrent parts it is not limited in its use to this connection.

The invention consists in the features and combination and arrangement of parts hereinafter described, and particularly pointed out in the claims.

Theobjects of 'the invention will appear from the detailed description ond from the advantages to be derived bv the use .of my invention, 4as will be referred to hereinafter. ln the accompanying drawings, Figure 1 is a longitudinal sectional view, partly in eleva.- tion, through the lubricator, showing n group of force-feed devices operated from a single shaft. Fig. 2 is a 'transverse sectional view, partly in eleva tion, of the invention with a dilferent form oi' nozzle -from that shown in Fig.' l. Fig. 3 is a plan view of the invention. Fig. 4 is u detail view, partly in elevation and partly in section, showing one forni of means for driving the eccentric-shaft. Figi 5 is e detail view inv section of the friction-clutch seen in E ig. 4. Fig. 6 is a view similar `to Fig. 2, showing a modified forni of adjusting means for altering the stroke of the pump.

In the drawings, l is a casing or reservoir for containing the supply of oil which is to be delivered by the force-feed devices to the This box or casing has bearings at 2, in which is journaled a shaft 3. This shzrf t in the particular embodiment of my in vention shown is employed to operate a plurality of force-feed devices, each of which is i intended to deliver its own supply to a certain partof the nnrohnie, though it will of course be readily understood that l do not limitniyself to any particular number of saidv devices, there being one or more. Esch force-feed device comprises a lixed piston 4, depending from the to plate ol` the box or reservoir into the oil t ierein, the said iixed piston being secured in position by screwing lts `upper end into what I term for convenience a nozzle 5, which in turn is held to Jelow the middle of the height thereof, and on this ixed piston e cylinder 7 reciprocates.

This cylinder at its upper end has e. stuffingbox '8, surrounding the fixedpiston, and etits lower end is provided wit a section 9, screwed therein and having a shoulder 10, 'fitting :against the end oi the cylinder proper. This section has its opening or 4passage oi' two diameters, the lower portion being ,of smaller diameter than the upper portion,l and at the upper end of each portion a valve-sent is formed for the small and large' checkvalves 11 and 12. A check-.valve 13 is also employed at the lower end of the xed piston, seid valve 13 restin on a seat formedby the rin portion 14, w lch is screwed into the sai fixed piston and provided at-its up er end with a seat for the said check-vs ve. All of the valves mentioned close downwardly upon their seats, and the same is true of a valve 15 etv the upper end of the part or tube constituting the nxed piston. All of the valves l prefer to' employ in the form of balls, and the upper valve 15 is pressed down against its seat by a. spring 16, saidvalve 15 end spring 16 being arranged inthe nozzle.L

The cylinder 'at its lower end is provided with e strainer 17, formed of wire-gauze or other suite-ble material in the form of acup, litted over the end of the cylinder and he d by o. portion of the wall ofthe strainer fitting i and extending laterally theref'roni,an to alsoA engage with a 19, formed or fixed onthe A end oi a screw 20, threaded through an erm 421, formed integral with the cylinder and ex tending laterally therefrom over the erm 18 and in the seine vertical plane therewith. The arm 21 is provided with an enlargement extending upwardly therefrom to aiiord ay icc long bearing for the screw to work through.

By turnin the screw through the said beering the dis 19 is 'adjusted vertically in relation to the eccentric, and as the length of stroke of the cylinder obviously depends eas,

40,passing through the lates and into lugs 41, projecting inwardly rom thesides of the reservoir It'will be seen from the above that the apparatus is free from com lication 0f parts,

and as contributing large y to that end the straight fixed piston of tubular form dependin into 'the reservoir and the reciprocating lcy inder on the said straight piston are elements of importance. The fixed piston forms a straight and uninterrupted passage for the initial outflow of the oil from the reservoir, the said oil passing upwardly fromthe reservoir through the said iston'and immediately into the pipe or con uit leading to the part to be lubricated. This straight construction of the discharge-tube maintains an even pressure on all the valves, as there are no corners for the Huid to press against.v Moreover, this straight construction facilitates adjustment and assemblage of the parts, The movement of the cylinder Within the reservoir serves to agitate the oil, and this is particularly the case with the strainer, which agitates the oil and keeps the same from thickening or clogging up. Each pump has its own strainer located on the cylinder thereof, and each strainer thus acts as a separate agitator and insures that the oil passing through the said pump is clear and free from thickened portionsor foreign substances liable to clog and linterfere With the perfect supply' of oil to the parts to be lubricated.

- One important feature of my invention is that the pum or forcing device comprising the v,piston-cy inder and its adjusting-stem can be removed as a whole from the reservoir, and where a plurality of pumps are employed, as shown in the illustrated embodiment of my invention, each pump may be removed independently of all the other pumps. This is done simply by loosening the screws holding the particular section of the top plate which carries the said pump and its adjusting mechani'smg'and by merely moving the pump laterally it may be readily detached from the eccentric and then lifted out of the reservoir 'and its adjusting-stem and adjustable disk are removed at the same' time, all being suported from the same section of the top plate.

he Whole device may thus be removed and replaced without changing the relative position ofthe parts, it not being necessary to alter the position of the`disk in relation to the eccentric'. In replacing the pump or forcing device an operation the reverse of that above described is performed.. The removal of the pump may become necessary or desirable for a variety of causes-such, for instance, as cleaning the valves, cleanin the strainer, Which may have become fille up or clogged with any foreign substance, or for setting up the stuffing-box or making other adjustments of the parts. 'Ihe feature which renders the cee 3f;

stems rise through the top plate of the casing A and work looselgy therethrough, the sleeves before mentioned being smooth on their eX- terior and moving through openings in the said top plate. As the eccentrics operate the pumps the adjusting-stems move up and down through the top plate, and thus they show the amount of throw that each cylinder has according to the particular adjustment of the arts of each pump. The verticallyqmovab e stems thus serve as indicating means, whereby the operator can tell apjroximately how much oil is being forced om the reservoir through each pump, and he can then make adjustment of the pumps individually as maybe req uired. Each valveseat of any one of the pumps is freelyA accessible by removing certain of the parts. This applies to the upper valve as Well as to the two lower valves` oil that should Work up through the stuffing-boxes of the pumps returns to the reservoir, as all the Working parts of the pumps proper are in the reservoir. This return of the oil is due also to the fact that the cylinders reciprocate 'entirely Within tla reservoir and no part thereof extends outsi e.

Instead of using a solid screw-stem, as above described, l may employ the arrangement shown in Fig. 6, in Whicllthe screwstem, carrying the disk at its lower end for the eccentric to Work against, has a reduced extension 42 at its upper end, which enters a socket 43 on the lower endgo'f a stem 44, Which passes through the top plate of the apparatus. By turning this upper stem 44the lower screw-stem Will also be operated, and as this is threaded through the arm 21 said stem, with the disk thereon., will be adjusted toward or from the eccentric. The parts may be locked in position by a set-nut 23, resting on top of the reservoir, engaging a threaded portion of the upper stem.

- Excepting Where it is specically hereinafter noted ,in the claims I do not wish to limit. all the features of my invention to the vertical arrangement of the pump Within the reservoir, as other arrangements may be used Without departing from some of the features of my ,invention Instead or driving the shaft as aboveI described it maybe driven by Worm-gearing from a lfelt. or sprocket-Wheel.

The connection between the pump and its removability of the pump'possible consists of operating means maybe said to be a-loose one, .in that alle pomp may be disconnected tliereiron'i by o lateral movemen of the pump in relation to its o without requiring' any jov oir? oisconnected Wil'iin the i'esevvoir.
